Abstract

The invention discloses a laser radar, equipment and a laser radar installation angle calibration method. The laser radar comprises a tilt angle sensor, a controller, a driver and a scanner, wherein the tilt angle sensor, the controller, the driver and the scanner are sequentially connected in series; the tilt angle sensor is used for detecting an installation angle of the laser radar; the controller is used for obtaining an actual deflection angle of the scanner according to the installation angle and a target inclination angle of a laser beam emitted by the scanner, and generating a drivinginstruction carrying the actual deflection angle; and the driver is used for driving the scanner to deflect the actual deflection angle according to the driving instruction. According to the technicalscheme provided by the embodiments of the invention, the automatic compensation of an installation error of the laser radar is realized, no manual consumption is generated, the man-hour is short, andthe measurement and debugging precision is high.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of laser radar, and in particular, to a laser radar, equipment, and a method for calibrating an installation angle of the laser radar. Background technique [0002] Lidar is a radar system that emits laser beams to detect characteristic quantities such as the position and speed of the target. Compared with ordinary microwave radar, because it uses laser beams, its operating frequency is much higher, and it has high resolution and concealment. Good, strong anti-interference ability, small size and light weight and other advantages. [0003] LiDAR is usually installed on a fixed plane. For example, it is installed on the top of a vehicle. Due to the influence of the installation environment and other conditions, installation errors will occur. Installation errors will affect the detection range of LiDAR, especially the pitch error. The impact is more significant. In the prior art, after ...
